# Localizing invoices and credit memos

To control how [purchase invoices and credit memos](/digital-river-api/order-management/accessing-invoices-and-credit-memos.md) are localized, you can define the checkout's [`language`](#language) or its [`locale`](#locale).

## Language

If you send a [supported `language`](#supported-languages) in a [create](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/checkouts#checkouts-1) or [update checkout request](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/checkouts#checkouts-id-1), then Digital River maps it to one of our [supported locales](#supported-locales) and uses that value to set the [checkout's ](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/checkouts)[`locale`](#locale).

### Supported languages

For a list of accepted values, refer to [Supported languages](https://docs.digitalriver.com/digital-river-api-reference/digital-river-api-reference-guide/supported-languages).

## Locale

At the time of order creation, Digital River uses the [checkout's](https://docs.digitalriver.com/digital-river-api-reference/2020-12-17/checkouts) `locale` to set that same attribute in the [order](https://docs.digitalriver.com/digital-river-api-reference/2021-12-13/orders), determining how [purchase invoices and credit memos](/digital-river-api/order-management/accessing-invoices-and-credit-memos.md) are localized.

The default value is `en-US`.

### Supported locales

The following table lists all the `locale` values, which combine a two-letter [ISO 639-1](https://en.wikipedia.org/wiki/ISO_639-1) language code with an [ISO 3166-1 alpha-2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) country code that Digital River supports:
